The simplest way to shield your hair is to literally shield your hair. Wearing a hat or scarf over your head when you’ll be outside for an extended period of time is a fail-safe way to keep your strands shielded from pollution. Even pulling your hair back into a knot or bun will provide some protection, as the hair wrapped in the bun is largely unexposed.
Using finishing products like pomade and styling cream may make your hair more vulnerable to buildup because these stylers can impart a tacky surface on strands that makes it easy for grime to stick. A better bet: Use lightweight, easily-absorbed serums or lotions to add shine or fight frizz. And, if you just can’t give up your heavier stylers, take cover (as outlined above).
It sounds counterintuitive to shampoo less frequently when buildup is an issue, but because pollution dries out your strands, excessive washing can exacerbate the problem. As a rule of thumb, wash no more than once a day, and when you do wash, focus shampoo on the scalp, allowing it to run through the rest of your hair only as you rinse it out. Using a shampoo designed to deep clean without stripping oil (i.e. a sulfate-free shampoo) will also give you more bang for your sudsing buck. And, if you must take a second shower (like if you worked out or you commuted home in sweltering heat), just rinse your hair with water sans shampoo.
Help your hair help itself
Using shampoo, conditioner and a treatment mask that boost your hair’s moisture level and infuses it with strengtheners will make it less vulnerable to environmental assaults. At Prose, when we formulate your custom hair care, we take into account the pollution levels where you live. People in urban areas may get an extra dose of horehound extract, which protects scalp skin from pollution penetration, as well as strengthens and repairs the hair—or a blend of hyaluronic acid and lilac extract, which increases moisture and improves elasticity, helping to counteract the brittleness (and breakage) that pollution can cause. We’ve also just revamped our scalp mask to include jojoba beads for gentle exfoliation and eucalyptus and grapefruit essential oils for freshness.
Because pollution can compromise your hair quality, it’s imperative that you treat it with extra care. When detangling, use a wide-toothed comb and start at the ends of your hair, working your way up to the roots. Giving your hair a break from heat styling if possible is also a good idea, though may not be realistic for some. When you do blow-dry and/or flatiron your strands, always use a heat protection product, snap the nozzle on the end of your hair dryer to limit heat exposure and use straighteners and curlers at a temperature no higher than 360-400 degrees. For those who regularly heat style, we will often add wheat and soy amino acids and arginine to provide a protective shield against the heat.
